The whole "time travel" and "time dilation" when basing it on einstein general relativity are such a bs concept from my perspective ngl.
For what i know, the concept of so called "time" is that they were invented by "us", and we did the measurements based on the action done by an object we're observing.
Like when we decide in older times that a day = a night and a day,
As our measurements progress, we now decide that an atomic clock is our most "precise" measurements of time.
Note the "precise".
if the time itself is human relative.
And it will slows down when we move arround (look up "photon clock" and "einstein time dilation theory" for more detailed information.)
When in "reality" the "actual time" does not and hoping you can travel back in time using black hole as a medium or some whacky ideas is just sad.
Further note. Try not to think that reality (gravity, matter, etc) exist as in a "fabric", that's how most physicians told you when they themself knows that the word "fabric" are going to make a lot of missunderstanding (fabric = 2d? Get it?).
Gravitational force is 3d, that's why it will catch anything regardless of your relative position (up, down, left, right).
I'm open for someone to lecture me on this concept.
Further note.
i agree, you will age slower. But that doesn't mean you can travel back in time. You just experience time differently because of every atom in your body and your environtment (that were moving relative to something) need to travel further distance.
Am i overthinking it?
Will this help our current research?
I'm being unproductive.
Help 
@deesapoetra a lot of misconceptions in this thread. However, I'm exhausted today + I'm not a physicists so I'll let someone else explain it. Perhaps @freemo has time?
🇳🇱
I'll take a shot...so a few misconceptions here. First off you talk about traveling back in time, that isnt related to time dilation, that only slows time.. time travel on the other hand is far more theoretical and would require things to be true that go well beyond simple general relativity.
That said im not sure why you would say general relativity is bs the precision of time isnt the issue, if time dilation is great enough it would have an effect on even impercise time keeping devices.
@freemo @zpartacoos no. I never said General relativity bs Mr. Freemo. I said "time dilation" when basing it on "general relativity", when we don't know yet on how to accurately measure time without making the "measurements device" slows down.
Feel free to correct my missunderstanding and pardon my english, i'll occassionally rephrase my sentences.
Time Dialation is dictated by general and special relativity. We know perfectly well how to measure time acurately without the measurement device slowing down, its not the measurement device slowing down, time is slowing down. So it is measuring the actual time.
Your misconception seems to be in the idea that there is one correct time that is the same across all frames of reference, there is not. Its no different than the fact that there is no privileged velocity and no absolute idea of "stationary" either.
@freemo
would you mind dropping some paper regarding "time is slowing down" later Mr. Freemo?
I'm interested since i can't find any video on youtube that mention any research regarding "time dilation". (I know. It's stupid to use youtube as your information source. But for what i can te you. Some channel are kind enough to link some paper related to the video topics).
@deesapoetra well, you'd need some pretty advanced math to fully understand relativity. You could probably get through special relativity with just basic math, but not general.
Atomic clocks are a fairly accurate measure of time, more precise than any clock we have, they show time dilation. It also doesnt require anything to move. time dialation happens between something stationary but closer or farther from a planet. For example if you take an atomic clock and put one in a valley and the other on the top of a mountain they will tick at different and predictable rates according to time dialation.
Second, no freezing something to absolute zero wouldnt prevent time dilation , in fact temperature doesnt have an effect on it at all. For example you could see observe time slowing down by chilling radioactive material to near absolute zero and observing its half life, which will speed up or slow down according to the time dilation.
@freemo
I managed to find the information regarding "how all clocks the same."

@deesapoetra How does that matter? The clock isnt important, you can use anything to keep time you'd like, the effect is the same.
@freemo
> you'd need some pretty advanced math..
i'm always fine with math. Idk for physics tho'. I never liked it.
Anyway.
for what i understand (from a lot of information that related to time dilation). People trying to prove time dilation using this analogy.
"A moving photon clock is moving slower relatively to the stationary one because they need to travel further distance and it would results in "time" being slower. Therefore time dilation is real"
(And photon clock aren't so different from any clock too. I can't remember the exact explanation. I'll re-visited my internet history to see if i still got it.)
I'm so bothered by this concept.
If there's indeed an accurate measurements of time i would like to know where to find it.
Until then, i consider "time dilation" that results to a "time travel" (if we're able to move at such high velocity, by that argument traveling back and forth in space would bring you to the future faster and freezing matter to a/near absolute zero would stop/slowed the object from experiencing time.)
